Comfortable GUI application to edit the contents of various Bitcoin wallet files, add or remove keys, read one format and export to another, move keys between different wallets, etc.

how to build from source

  • have JDK 7 installed (6 will not work)
  • clone this repository
  • in the root directory execute:
    ./gradlew assemble

you will find the runnable .jar file in build/libs/

I'm too lazy to build it myself, where is the jar?

See the releases section and look for the "wallet-key-tool.jar" file, download and run it as described below.

This release version might be a bit behind the latest master branch, so I recommend you get the source and build it yourself, its really not that complicated, the gradle build system does a wonderful job of automating it all, you don't even need gradle to be installed, it will download it for you.

how to run

On Windows you probably just need to double-click the jar file and it will start (If you have Java installed).

On systems where there is a command line interface (this also works on Windows, its just a bit harder to find there, they really seem to hate their own users) you can also run it by executing the following command:

java -jar wallet-key-tool.jar

This will open a GUI window with which you can interact, info and error messages will be printed to stderr. If you want to increase the log level then run it like this:

java -Dorg.slf4j.simpleLogger.defaultLogLevel=TRACE -jar wallet-key-tool.jar

Note: the -D option must come before the -jar option, it is passed directly to java. Allowable log levels are: ERROR, WARN, INFO, DEBUG, TRACE, the default is INFO, if you want to see stack traces then use TRACE.

If you just want to dump the contents of a wallet to the console with no GUI interaction then you can pass it a file name, if you do this then it will not attempt to open any graphical user interface, it will just dump the wallet contents to stdout and exit. Note that the format of the dump is still subject to change, keep this in mind when writing a parser for it.

java -jar wallet-key-tool.jar <filename>

This will prompt for a password on stdin if the file is encrypted. If you want to avoid the password prompt you can supply a password with the --password="my pass phrase" switch (you need the quotes if it contains spaces). Beware that this is dangerous since it might leave the password in your shell history or make it visible in the process list, use it only if you know what you are doing.

Example session in the console (I did not enter a passphrase, I just pressed enter, so no private keys were decrypted):

java -jar build/libs/wallet-key-tool.jar /home/bernd/Schotter/Schotter.wallet
[main] INFO org.multibit.store.MultiBitWalletProtobufSerializer - Loading wallet extension org.multibit.walletProtect.2
Wallet is encrypted. Enter passphrase:
no passphrase entered, will skip decryption
